Commuters on the Chicago Transit Authority’s (CTA) Red and Blue lines no longer face the frustration of outdated cellular infrastructure. Recent improvements to the 11-year-old system have upgraded communication and safety.

Funded through contributions from four major wireless network providers, this $32 million 4G upgrade enables riders to enjoy complete use of their cell and smartphones everywhere in the tunnel system. This is an advantage for CTA staff, contractors and emergency responders as well, providing for better coordination, more efficient use of their time and a safer work environment. Although contractor emergencies are extremely rare in the tunnels, contractors are now less reliant on CTA radios if an emergency should occur.

Arcadis provided construction management services for the design, procurement, construction and closeout of this project, which involved 12 miles of underground subway and 24 miles of individual tunnels. It’s a success that makes the ride to work, school or a meeting with friends and family all the more safe and enjoyable.
